Solar Buyback in Texas (2026): ERCOT, Retail Plans & the Self-Consumption Math

If you're a Texas homeowner thinking about solar in 2026, you're going to hear the phrase "no net metering in Texas" a lot. That's technically true — but it's also misleading. Texas doesn't have a statewide net-metering mandate, but a handful of deregulated retail electric providers offer their own buyback plans. The economics of your install hinge less on which panels you buy and more on which retail plan you sign up for AND whether you pair a battery.

Why Texas is different: ERCOT + retail deregulation

Texas is the only state running its own independent grid (ERCOT — Electric Reliability Council of Texas). 85% of Texans live in deregulated zones where they pick their retail electric provider (REP) — Oncor / CenterPoint / AEP own the wires, but you choose who bills you. The remaining 15% (Austin Energy, CPS San Antonio, co-ops, El Paso area) sit in regulated zones with utility-set buyback rates.

Because there's no PUCT-mandated retail-rate net metering, each REP sets its own buyback offer. The 2026 landscape:

The headline number is the export-credit rate. The thing nobody tells you is that most of these plans pair a "decent" buyback rate with an above-market energy charge for the kWh you import from the grid. Octopus is currently the cleanest spread; TXU / Reliant penalize you with monthly fees.

Side-by-side math on an 8 kW DFW install

Assume: 13,500 kWh annual production. Home uses 11,000 kWh. Exports 4,500 kWh. Install cost $24,000 before 30% federal ITC = $16,800 net.

With panel degradation (0.5–0.7%/yr) and 3%/yr utility rate inflation, realistic Texas payback in 2026 is 9–13 years for solar-only installs — substantially worse than the "5-year payback" pitches some installers still use from the 2015-2019 era.

The battery argument is different in Texas

Unlike California (where batteries shift solar to peak hours to dodge a 75% export cut), the Texas battery case is about ERCOT volatility:

• Summer afternoons — ERCOT wholesale prices can hit $5/kWh during scarcity events. A battery + smart export plan (Tier 1: Tesla Electric, Bandera Electric) lets you sell back at wholesale-linked rates during these events. One 2-hour ERCOT peak can earn $100-200 in a single afternoon.
• Winter resilience — February 2021 (Winter Storm Uri) cost the average Texan ~$1,200 in spoiled food + days of cold. A 13.5 kWh battery covers critical loads for 24-36 hours on a fully-charged unit.
• Solar-curtailment — many DFW / Houston solar systems get curtailed during the 11am-3pm window in spring/fall because ERCOT pays NEGATIVE wholesale rates. A battery soaks up the curtailed production for evening discharge.

Add a Tesla Powerwall 3 (~$14K installed in Texas) and the math gets reasonable:

What about Austin Energy, CPS San Antonio, El Paso Electric?

These regulated munis/co-ops have their own programs:

• Austin Energy — "Value of Solar" tariff (~9.6¢/kWh as of 2026, reset annually). Doesn't net-meter; you sell ALL solar at VoS, then buy ALL home use at standard tier rate. Worse than 1:1 net metering in most cases.
• CPS Energy (San Antonio) — Net billing at ~7¢/kWh export credit (avoided cost). Imports billed at ~11¢/kWh. ~4¢ spread is rough.
• El Paso Electric — 1:1 retail rate net metering still active (one of the few Texas utilities offering it). If you're in EPE territory, your solar economics look more like California's pre-NEM-3.0 era.

The 5-point Texas solar checklist for 2026

1. Confirm your zone (deregulated vs. muni) at the PUCT site. Your zone determines whether you can shop REPs.
2. If deregulated — switch to Octopus Energy BEFORE install, not after. Some plans require enrollment within 60 days of system PTO (permission to operate).
3. Size the system to your USAGE, not roof maximum. Texas-exported kWh earn 8–12¢ while self-consumed kWh save 14¢. Oversizing is mildly penalized.
4. Strongly consider a battery — both for ERCOT peak-event upside and Winter Storm Uri resilience. The 30% federal ITC applies to standalone batteries paired with solar.
5. Plan for the install timeline: ERCOT interconnection adds 6-12 weeks AFTER inspection in DFW / Houston. Don't sign a contract that imposes financing-rate-reset penalties if PTO drags.
